Abstract

The invention concerns a submarine cable having an optical fibre core. The core includes, as a longitudinal strength member of the core, a thermotropic plastics tube (8) having a generally rectangular-section longitudinal central passage and encased in a protective sheath (4), and at least one optical fibre ribbon (6), whose width is slightly less than the width of the passage, housed loosely within the passage, the ribbon (6) thereby being constrained to undulate in two dimensions in a longitudinal plane normal to its major surfaces. Preferably the tube (8) has a thickness substantially smaller than its width, so that its outer surface is also generally rectangular in section.
